Oil consumption!?
Heavy oil consumption in a 2001 Tahoe
5.3L 4WD A/T. Around one QT. per 700
miles. Not a leaker, other than a what
appears to be a small (?) Rear main leak.
Doesn't smoke upon startup. Steady normal
(above 40psi oil pressure when started.
Has great oil pressure all around. Does
leave a decent smoke cloud when taken
above 4000 rpm, suh as downshifting to
pass, etc. Seems EXTREMELY high
consumption to me. Has always used a bit
of oil every since i bought it at 52,000 miles
but has increasingly gotten worse, used to
be around 2000 miles I would need to add a
qt. Now has 207,000. Any thoughts ideas
other than new rings, etc would he greatly
appreciated. Thanks.
